As law enforcement officials continue to investigate alleged gunman Esteban Santiago, 26 -- the army veteran who opened fire in a baggage claim area, killing five and wounding six -- the families of the deceased are coping with their devastating loss.

ABC News has confirmed the identities of three of the five victims: Olga Woltering, 84, a great-grandmother from Marietta, Georgia; Michael Oehme, 57, a land surveyor from Council Bluffs, Iowa, who owned his own business, Boundaryline Surveys; and Terry Andres, 62, of Virginia Beach, Virginia, who was on his way to a cruise to celebrate his birthday; and Shirley Timmons, 70, from Senecaville, Ohio.

The church Woltering attended, Transfiguration Catholic Church in Marietta, posted a statement on its Facebook announcing her death, remembering her as a devout member of its congregation.

"Olga and her husband, Ralph, could always be found at 5:00 pm Mass, in the front of the Tabernacle side," reads the statement. "They were always happy and approachable!"

The Wolterings, who lived in a retirement community, had traveled to Fort Lauderdale for a cruise, according to The Associated Press, citing parishioners. Woltering's husband escaped without injury, according to ABC affiliate WSB-TV.

Woltering was active in the ladies auxiliary of the Knights of Columbus, a Catholic charity affiliated with her church, Roger Heil, the grand knight of the local Knights of Columbus group, told The Associated Press.

The church held Mass Saturday evening in Woltering's honor, according to WSB-TV.

"Olga Woltering was a loving wife, mother, grandmother, great grandmother and good friend to many," her son Tim Woltering said. She, along with our father, Ralph, is the cornerstone of our family and while she’s absent in our lives now, she remains in our hearts, thoughts and memories forever," said son Tim Woltering.

Woltering also had an outgoing personality and put family first, according to the church's Facebook post. "Olga was so charming, calling everybody 'Lovey' or 'Love' in her unmistakable British accent," the statement reads. "Her life revolved around her kids, grandchildren, great-grandchildren, and hundreds of extended family at Transfiguration."

The church's Father Fernando Molina-Restrepo said in the Facebook post, "Olga was one of the most joyful, loving, caring and committed people I have ever met. This is a horrible tragedy for everyone here at Transfiguration, especially because Olga was so loved. Olga and Ralph have been members of our Transfiguration Family since October 1978. May God give consolation to all of the victims of this tragedy and may God give eternal rest to those who died. Especially to our beloved Olga. Peace."

And church parishioner Alvin Connolly told The AP, "She and her husband were kind of the life of the party. They'd go to a dance, and they'd be the last ones on the floor."

He added, ""From what I understand, their sons are in Florida with her husband right now."

Another victim from the shooting attack, Michael Oehme, also headed to Fort Lauderdale for a cruise, with his wife Kari. She suffered a gunshot wound to the shoulder and is expected to recover, Michael's sister Elizabeth Oehme-Miller told The AP.

Oehme-Miller said the couple were slated to leave on their cruise on Saturday. "They were happy to be going on another trip," she told The AP.

"I still can't believe it's true," said Oehme-Miller, adding that another family member is flying to Fort Lauderdale to help Kari return home to Council Bluffs, "It hasn't hit yet. I'm kind of in shock right now."

And Deb Campbell, a friend of Kari, told ABC affiliate KETV in Omaha, Nebraska, "Not only will [Kari] have to heal physically but how do you heal a broken heart? ... Two people just trying to take a vacation get gunned down randomly not to mention the other poor souls who were also killed. Absolutely mindless."
